Punishment for Blasphemy

Leviticus 24

¹⁰ A man whose mother was an Israelite and whose father was an Egyptian came out among the people of Israel; and the Israelite woman's son and a certain Israelite began fighting in the camp. ¹¹ The Israelite woman's son blasphemed the Name in a curse. And they brought him to Moses--now his mother's name was Shelomith, daughter of Dibri, of the tribe of Dan-- ¹² and they put him in custody, until the decision of the Lord should be made clear to them.

¹³ The Lord said to Moses, saying: ¹⁴ Take the blasphemer outside the camp; and let all who were within hearing lay their hands on his head, and let the whole congregation stone him. ¹⁵ And speak to the people of Israel, saying: Anyone who curses God shall bear the sin. ¹⁶ One who blasphemes the name of the Lord shall be put to death; the whole congregation shall stone the blasphemer. Aliens as well as citizens, when they blaspheme the Name, shall be put to death.
